Controlling E9Screen EPC9 Installation 87
➐ When the user program wants to issue new commands, it writes a new
“command index” and the new commands to the “command” file, then
continues with step 5.
Here is an example of such a command file:
1. line: "1234"
2. line: "SetVHold -0.080"
3. line: "GetCurrentRange"
4. line: "MakeAnError"
And this would be the content of the “response” file:
1. line: "1234"
2. line: "CurrentGain 1.000E+09"
3. line: "unknown"
Error Messages
Errors begin with lower case letters:
'syntax' : parameter missing or misspelled
'range' : parameter is out of allowed range
'unknown': command is unknown
'ioerror': error during an I/O-operation
'unknown error': an unidentified error occurred
